Cutest Baby Animals at U.S. Zoos

Juba, Eastern Black Rhinoceros, Cleveland Metroparks Zoo

With the July 2012 birth of Juba, three generations of critically endangered eastern black rhinoceroses now call the Cleveland Metroparks Zoo home. (Juba’s mom is Kibibbi, and his grandmother is Inge.) Juba was about 80 pounds at birth, but is already growing up quickly. He weighs in at nearly 320 pounds now and will get to about 3,000 when full-grown.
